Answer:
Explanation:
(a). plotting using Excel sheet, we have the picture uploaded below
(b) The sample correlation coefficient is also computed using Excel Correlation function, given thus;
Admit Rate (%) 4-Year Grad Rate (%)
44 73
71 62
29 89
39 86
66 55
28 73
54 63
10 88
26 84
43 77
76 71
67 68
6 86
66 59
81 66
18 88
31 71
9 84
15 86
8 88
17 84
56 62
51 79
54 68
75 50
13 86
40 70
67 68
41 47
68 71
∴ The value of the sample Correlation Coefficient is = -0.76
This tell us that the two variables are moderately linear inverse correlated.
cheers i hope this helps.
Answer:
b. 10,000.
Explanation:
The number of units completed in April is given by the number of units on April 1st (3,000) added to the number of units started during April (11,000) minus the number of units still in production on April 30th (4,000):
10,000 units were completed during April.
Net Present Value is equal to the Present Value of the future cash flows - Initial Investment. The Present Value of the cash flows is discounted at an interest rate 15% (in the above question).
Present Value of the cash Flows = Cash flow in Year 1 ÷ (1 + r ) ^n
where r = 15%
n = number of years.
The Net Present Value is $1,328
